Berggren said ACT and AP testing is soon to be underway in the Chandler Unified School District, which is one of many districts planning to close for the walkout.

AzMERIT

AzMERIT English and math tests are administered to students in third grade through high school.

The testing window for AzMERIT tests is governed by state statute and extends until April 27, according to the Arizona Department of Education. Test results can impact a variety of things, including teacher pay and school funding.

Approximately 65 percent to 70 percent of schools had completed testing as of last Friday, according to Arizona Department of Education spokesman Stefan Swiat.

Schools closing for the walkout that have not already finished AzMERIT tests might have their testing schedule affected.

Test scores and assessment data from the third-grade reading portion must be received by local education agencies on or before May 15, and from all other portions of the test on or before May 25, according to state law.

The state board must impose penalties on the contractor for scores received after these dates, according to state law. But the Legislature could extend the deadlines, Swiat said.

ACT and SAT

College exams such as the ACT and SAT are typically administered outside of school hours, but are often held on school grounds.

ACT test centers may cancel a test due to unforeseen circumstances, according to the American College Testing website.

Tests will be rescheduled, and students will be notified via mail or email with instructions about their new test date.

The location of the test center would not change for rescheduled test dates unless otherwise noted.

SAT testing is scheduled for May 5 and June 2.

In the event that a test center for the SAT is closed, information about makeup testing and new test centers will be posted online.

Advanced Placement exams

Many high school seniors are in the midst of studying for advanced placement exams, which give them college credits.

AP exams are not immediately impacted by the walkouts. The first week of AP exams is scheduled for May 7-11 and the second from May 14-18.

Students routinely conduct practice testing before their actual exam. Practice testing may be affected by school closures.

"Should schools continue to be impacted by a walkout, TUHSD will ensure that this testing still takes place," said Tempe Union High School District in a statement to parents Monday.

Gilbert Public Schools, which will also be closed, released a statement saying AP testing would take place at students’ schools as scheduled.

But Berggren, with Chandler High, said studying students may be impacted by losing important study time.

"Any progress that we might have made toward helping them graduate or meet their goals might be lost because I don't know how long this is gonna go on," she said.
